My name is Nyajuok Wur. I am originally from South Sudan, born in Ethiopia, raised in Minnesota and currently living in Houston, TX. My passion for medicine began at a young age and my desire to help others continues. I chose family medicine because of the variety as well as the opportunity to work with people from all ages and backgrounds.

Hobbies outside of medicine include reading mystery books, international travel, and singing.

I enjoy practicing all aspects of Family Medicine. I am board certified in Family Medicine, and have been in practice for over 40 years. I recently joined the primary care clinic in Angleton and enjoy it very much. It reminds of the small town I grew up in, in Oklahoma. I especially enjoy the drive over along the Bluewater highway.

My wife and I moved to Galveston in 2003. We love living on the beach and visiting our grandchildren.

My name is Casey Buck. My clinical areas of special interest are preventative healthcare and Family Medicine. I enjoy spending quality time with friends and family. I am an avid Houston sports fan, dedicated husband, and dog Dad.
